A cyclist taking part in RideLondon has died after collapsing during the event.

Kris Cook suffered a heart attack 46 miles into the ride while attempting to climb a hill on Sunday afternoon, at around 1pm

The civil servant was riding with his girlfriend Nicola Tait and a group of friends to raise money for Woking and Sam Beare Hospices, in Woking, when he complained of sharp chest pains at the bottom of the hill.

The last thing he said to partner Nicola was 'I'll meet you at the top of the hill Nic, on the left-hand side' and she arranged to meet him there but, shortly afterwards, he collapsed.

Nicola, 35, was told by a friend that Kris had come off his bike.

Speaking to Get Surrey, she said: "There were no paramedics at the top of Newlands Corner, just a couple of support vehicles and he was given mouth to mouth while we waited 20 or 30 minutes for the ambulance to come.

"The paramedics gave him electric shock treatment then he was taken to hospital.

"I had to go home and wait. The police called and came round to see me and I also spoke to a Prudential organiser who had a medical background and said the situation was looking grey."

RideLondon organisers said he died in hospital after being treated at the scene by doctors.

Mr Cook was one of thousands of riders taking part in the Prudential RideLondon-Surrey 100.

The event was shortened from 100 miles to 86 amid forecasts for bad weather as the effects of Hurricane Bertha's remnants were felt in the UK.

Mr Cook was part of a group of 12 riders raising money for Woking Hospice.

According to the event's organisers, his mother said he died "doing something he loved".

She welcomed donations in his memory to his fundraising page at www.justgiving.com/Kris-Cook where her son previously wrote: "I have never taken on a challenge such as this."

A spokeswoman for Prudential RideLondon said: "Kris Cook, aged 36, collapsed at Newlands Corner from a sudden cardiac arrest and, although prompt medical attention was provided by event doctors on the scene, his death was later confirmed after further attempts to revive him at hospital."

She added: "The organisers of the Prudential RideLondon-Surrey 100 would like to express their sincere condolences to Kris's family and friends."

A post-mortem examination will be carried out to establish Mr Cook's cause of death.
